This ring has been an absolute game-changer for me; I've had issues sleeping my whole life, and have taken every sleeping pill on the planet, including all the heavy/narcotic ones, and I was sick of not being able to rest for days if I forgot/lost them, couldn't fill the Rx, etc. I also recently started getting back into running for the first time since high school (I'm in my mid-30s). this app's ability to tell EXACTLY how I'm sleeping (light/deep/REM/awake), and give insights as to how my activity might be helping or hurting my ability to be well-rested the next day, is truly incredible.
Simply by wearing this regular-looking (stylish even!) ring, which is water+everything-proof, and has a full week-long battery, I can track EVERY step, heart beat, breath, and nap. I'm now completely off of all my sleeping pills (I was on seroquel, klonopin, and Ambien!), exercising comfortably (usually not more than Ours says is necessary that day), just overall living a MUCH healthier life!
My only feature request would be to be able to MANUALLY SELECT WHICH RESTFUL PERIOD IS COUNTED AS YOUR SLEEP EVENT! I often work crazy hours, and if I nap from 1-2am for example, that'll sometimes get counted as my sleep for that day, not my actual sleep from 7am-2pm (which IS recorded properly as a "restful event", but with only a single HR/HRV value). Other than that, it's perfect!
